After planning for nearly a decade — and beating back implacable NIMBY opposition — Fordham University this afternoon will break ground on an important expansion of its West Side campus.

Good for Fordham, even better for New York City — and too bad about those NIMBYites.

The expansion, adjacent to Lincoln Center, eventually will allow the university to accommodate 11,000 students, up from 8,000.

In a nutshell, the city’s lucky Fordham never wavered in years of opposition.

The obstructionism took many forms — though it largely originated with locals complaining that high-rise buildings would interfere with their precious sight-lines.

And, as always, so-called community leaders tried to pry as many concessions as possible from the school.

Never mind that education and technology are growing fields of importance — to New York and the nation — and that Fordham attracts first-rate students nationwide and globally.

Again, Fordham pretty much held firm — allowing university President Fr. Joseph McShane’s vision to carry the day.

(That City Council Speaker Christine Quinn and Manhattan Borough President Scott Stringer both began entertaining dreams of citywide office when the project was finally approved probably helped nudge things across the finish line.)

So congratulations to Fordham. This particular addition to the city’s assets has been a long time coming — but it’s been worth the wait.
